Copper ions can penetrate into the outer membrane of microorganisms, causing the loss of important nutrients in the pathogenic microorganisms and the interruption of cell metabolism, and ultimately the death of the pathogenic microorganisms, so it is widely used in the disinfection process. From the recent verification and report issued by the State Key Laboratory of Emerging Infectious Diseases of the University of Hong Kong, it can be seen that the copper-infused fiber material can reach or close to 100% of the new coronavirus with a titer of not higher than 104 PFU/ml within 10 minutes. Inactivation efficiency. For the new coronavirus with a titer of 105 PFU/ml, the effect of nearly 100% inactivation of the virus can be achieved within 60 minutes. Because the effective time of copper ions in the fiber is very long, the mask can be used repeatedly.

Qingbomei antibacterial protective mask uses copper ion antibacterial, and uses high-efficiency and low-resistance filter materials and recyclable skin-friendly pure cotton materials. It is anti-bacterial, anti-viral, and highly effective in filtering particulate matter, PM2.5, etc. It is a new type of cotton KN95 mask that can be recycled. At present, the company's mask has obtained relevant patents and has been exported to the United States, France, Britain and other countries.
